    Roof Facing Question

    I agree that the best way to get more information is to get some quotes from solar installers. However, you can get some information online from Project Sunroof (I found Google's estimates to be on the low side). Plugging data into PVWatts is likely easier after you've gotten some estimates...

    Solar Glass Snow Avalanches

    I got solar + powerwall through a local installer and they mentioned these snowguards (https://www.alpinesnowguards.com). The recommendation at the time was to get a 'bar style' that are mounted to the panels over my driveway. The other panels aren't over any high traffic areas so I didn't...

    Gateway solar reporting

    Yeah, I believe there is a separate load CT in addition to the solar CT. Thanks for confirming that you're seeing negative values. I'll keep digging to see why I'm not seeing negative values.

    Gateway solar reporting

    Does the call to /meters/aggregate for the "instant_power" value for the "solar" meter always return a positive value? My solar CT is located on the feed from the solar combiner panel. As such, when there is no solar production, there is actually a small power draw from the solar side (the...

    SPAN - Smart Electrical Panel

    There is another product out there: Lumin® : Responsive Energy Management Platform It sits outside of the panel and only has a limited number of slots so you can't have every outlet monitored by it.

    Existing Powerwall 2s to get 50% power capacity increase with SW update?

    Yes, that was the point of my query. Since I'm still waiting for the powerwalls to arrive and be installed, is there any benefit in installing the appropriate wire and breaker sizes for the rumored increase? Thus, if the rumor somehow becomes reality for new installs then I can take advantage...

    Existing Powerwall 2s to get 50% power capacity increase with SW update?

    According to the original article, the tweet from Musk said: So my question is has this been unlocked for anyone? In particular, it seems that unlocking a 50% power increase could be problematic because of the wiring / breakers currently in place. If I am misinterpreting the tweet, I'd...

    Existing Powerwall 2s to get 50% power capacity increase with SW update?

    As I'm still waiting for my powerwalls to come in, I'm wondering if it is worth installing breakers/wiring to support the 50% power increase (Existing Powerwall 2s to get 50% power capacity increase with SW update... )? On one hand, assuming the cost isn't that high, it seems like it would make...

    Ford Bi-Directional Charger for Ford EVs (and maybe Powerwalls?)

    FWIW I believe the Wallbox Quasar is being sold (or will be sold "soon") in the US and has already been sold in Europe and Australia. My understanding is that the use of this with the Nissan Leaf doesn't void the warranty on the car. The output numbers aren't as good though. I agree completely...

    Cooling SE Inverter with external fans

    I'd agree that moving the air across all the fins would make the most sense. Do you have an IR camera? I'd wonder if there was an area/fin hotter than the rest. ...A somewhat off the wall idea - if you were looking to decrease the temperature more, have you thought about using a Peltier...

    Cooling SE Inverter with external fans

    Did you cut into the top case with the shroud or is the only gap in the area in the back? If you didn't cut into the top case to allow the fan to blow unimpeded into the unit, I'm wondering if you're generating a bunch of turbulence that is hampering smooth airflow in/out. If you are blowing...

    Ford Bi-Directional Charger for Ford EVs (and maybe Powerwalls?)

    Are there that many free charging stations these days? I certainly don't mind paying for the electricity in this scenario and would likely be willing to pay more, especially since I'd hope this wouldn't be necessary more than say once every couple of years.

    7.6kW PV per PowerWall also applies to Plus?

    Does the PowerWall+ have the same recommendation for 7.6kW of PV per PowerWall? I saw another thread that this is more of a 'rule of thumb' than something specific. The PowerWall+ specs on the web page say 7kW continuous power and 10 kW peak so wouldn't this mean that so long as (PV...

    Ford Bi-Directional Charger for Ford EVs (and maybe Powerwalls?)

    I really like the idea of V2H and having that combined with PowerWalls. In particular, in my case, my power outages have generally been fairly isolated and so being able to go out and charge my vehicle and bring back electricity to the house seems like a great idea.
